In plain English

Supreme Source Grain-Free Turkey Meal & Sweet Potato Recipe is a dry food featuring turkey meal as its main protein source.

This formula includes quality fat sources like named chicken fat and marine oil, which provides beneficial EPA and DHA. It also uses premium micronutrient forms, such as chelated minerals, for better absorption.

The biggest concern here is the lack of an AAFCO statement, which means its nutritional completeness is unverified. Also, there's high legume stacking with peas, chickpeas, and fava beans all appearing in the top ingredients.

Good fit for dogs whose owners prioritize turkey. Less ideal if you prefer foods with AAFCO verification or lower legume content.

Who this is for

Good fit for adult Labrador Retrievers navigating weight management. At 381 kcal/cup this formula runs on the moderate side, with crude fiber at 8% (above the catalog median, supports satiety). The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. According to the Association for Pet Obesity Prevention's 2023 survey, 59% of dogs in the United States were classified as overweight or obese by their veterinary healthcare professional, representing an estimated 55 million dogs  (APOP, 2023) .

Research informing this analysis

Methodology

The Sniff System grades this product against 3 cited studies relevant to its profile. Each link opens the original source.

Every claim on Sniff traces to a source. If you find a citation that's wrong, outdated, or misapplied, tell us.

Why this score

Sniff scored this formula 57/100, landing in C-tier (acceptable-with-notes). The biggest contributor was fat quality (+12 points): Quality fat sources: named fat with marine oil (EPA and DHA source). A hard cap of 59 also applied because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). If the brand publishing the AAFCO statement were on the label, the cap would lift and this formula could clear the B-band threshold (60).

What lifted the score

Quality fat sources: named fat with marine oil (EPA and DHA source).

FQI

Premium micronutrient forms such as chelated minerals or natural vitamin E.

MNI
What pulled it down

Score capped at 59 due to no AAFCO statement.

CAP why?

No AAFCO statement. Nutritional completeness unverified.

ACF

Contains high legume stacking. Multiple pulse-family ingredients in top 15. Mitigated by taurine supplementation or organ meat (natural taurine precursor) in top 10..

CIP
What sets this apart
  • Top 10% for crude fiber in grain-free dry kibbles (8.9% DMB)
  • Bottom 10% for DMB fat in grain-free dry kibbles (12.2%)
  • Bottom quartile for protein quality in grain-free dry kibbles (10.3/27)

Ingredients

51 total
Good Neutral Watch Flagged
  1. 1
    turkey meal

    Turkey with the water cooked out. Per pound, packs more protein than fresh turkey. See why →

    Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.

  2. 2
    peas

    Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →

    Position 2. Pulse-family ingredient this high in the deck is a notable build choice. When stacked with other pulses in the top 10, matches the formulation pattern the FDA flagged in its diet-associated DCM investigation.

  3. 3
    chickpeas

    Also called garbanzo beans. Affordable plant protein source, part of the legume stack the FDA examined in its heart-disease investigation. See why →

    Position 3. Pulse-family ingredient this high in the deck is a notable build choice. When stacked with other pulses in the top 10, matches the formulation pattern the FDA flagged in its diet-associated DCM investigation.

  4. 4
    sweet potato

    Complex carb with fiber and beta-carotene. Gentle on the stomach.

    Position 4: meaningful whole-food inclusion. Source of vitamins, antioxidants, or natural fiber.

  5. 5
    chicken fat

    Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →

    Position 5: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.

  6. 6
    fava beans

    Less common pulse. Same concern as peas when stacked with other legumes.

  7. 7
    canola meal
  8. 8
    flaxseeds

    Plural form, same as flaxseed. Plant source of omega-3, helpful for skin and coat.

  9. 9
    dried plain beet pulp

    Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality. See why →

    Position 9: functional fiber for digestion or satiety.

  10. 10
    pea fiber

    Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.

    Position 10. Moderate inclusion. Contributes carbohydrate and some plant protein.

  11. 11
    pea starch

    Refined starch from peas, mostly carbs after the protein is removed. Counts toward the legume stack the FDA examined.

    Position 11. Trace inclusion. Below the level associated with the FDA's DCM-pattern concerns.

  12. 12
    natural flavor

    Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.

  13. 13
    dicalcium phosphate

    Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.

  14. 14
    salt

    Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.

  15. 15
    potassium chloride

    Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.

  16. 16
    fish oil

    Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.

  17. 17
    dried seaweed meal
  18. 18
    l-threonine

    Essential amino acid. Sometimes added when plant proteins dominate, since threonine is naturally lower in plants than meat.

  19. 19
    taurine

    Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.

  20. 20
    dried chicory root

    Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.

  21. 21
    choline chloride

    Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.

  22. 22
    dl-methionine

    Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.

  23. 23
    blueberries

    Antioxidants, real. But the amount in any kibble is too small to do much. Mostly marketing.

  24. 24
    carrots

    Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.

  25. 25
    cranberries

    Often added with a urinary-tract-support marketing angle. Real cranberry compounds help in concentrate form, but kibble doses are small.

Showing first 25 of 51. Position 1-5 has the largest weight in the recipe.
